At the start of the first season, Usagi & co are 13 and Mamoru is 17, and by the time Sailor Moon R rolls over, Chibiusa comes from the future as a 6 year old, Usagi is 14 and Mamoru is 18. In the third series, Usagi turns 15, and Mamoru turns 19. Chibiusa returns as a 7 years old, Setsuna is 18, Haruka and Michiru are 16, and Hotaru is 13. At the end of the third series, Hotaru is rebirthed as a baby. At the beginning of the fourth series, Hotaru is 1 (cronologically 14), Usagi is 16, Mamoru is 20, Setsuna is 19, Haruka and Michiru are 17, and Chibiusa returns as a 8 years old. When Hotaru s’ powers “wake-up”, she turns into a 8 year old and stays that way. At the end of the fifth series, Usagi is 17, Mamoru is 21, Setsuna is 20, Haruka and Michiru are 18, and Hotaru is 9 (actually 15). A few months later, Usagi gets pregnant, and the New Crystal Millennium starts. Everyone gets encased in crystal and the Sailor Senshi become immortal. By then, it’s been 1000 years, but Usagi is 22, Mamoru is 26, Setsuna is 25, Haruka and Michiru are 23, Hotaru is 14 (actually 1020), and Chibiusa is 5, and their ages have been stopped, but if Usagi gets killed in battle, over-uses the Silver Crystal, or abdicates, then Chibiusa would be next in place and age up into whatever age she would be if their ages were not locked and the crystal-encasing did not happen.

I beleive the reason why she did not grow up to her full age was because Galaxia needed her star seed to mature. She needed to age a certain amount for the seed to mature which explains the fast aging and the fast ending of it.Galaxia mentioned that slightly when Saturn/Hotaru was ready to destory her.
I wish we got a transformation and attack from her, just one.
Love this comic!!!

Yah, <3 Hotaru-chan. I actually like her as her slightly younger self in Stars- so adorable. I don't know why she didn't grow up to her old age though, in the manga it looks like she does but in a lot of shots than she still looks young.

LOL that’s great! I wondered the same exact thing, why didn’t she end up growing at least up to how old she was in S. It would’ve been cool if she aged up to everybody else, but it shows that size doesn’t always matter, she kicked a lot of butt anyways! She was about to put Nehelenia in check before Chibiusa stopped her. My favorite part is the last shot where Hotaru is still wearing the same smile she had before, as if she didn’t move an inch since last time. Setsuna’s comment is hilarious as well:)

I don’t have any word to express how funny this comic is…
I LOVE IT <3 I guess this is the best comics you have ever done (the rest are awesome but this is the funniest LOL)
Honestly, I have never thought about not Hotaru's growing up in this way. You are really clever and observant ^^
Really a great work..

I wish they’d make her grow back to the age when Sailor Saturn first appeared in Super season. I mean, even if they were reborn, it’s not like we’d see say a ..8/9 year old Sailor Jupiter for example ^^;

I have to tell you, I am in love with MoonSticks! Every single comic is hilarious and adorable! I also love how you even have the outfits accurate — Like in comic #1, that’s what they were wearing that episode! So awesome and detail oriented.
Love it!
